Hi @Mariusz - thank you for the bug report. That certainly sounds like a kernel bug based on your description.
Doing a kernel bisect is probably the fastest approach to identifying the offending change. There are 392 changes between -136 and -142 so it could take up to 9 tests for a full bisect. @Mariusz, is it possible to find out which (if any) of the intermediate kernels between -136 and -142 are affected ? If you don't have any of the intermediate kernels installed already, you can install them with a command like this one: sudo apt-get install linux-image-4.15.0-137-generic linux- headers-4.15.0-137-generic linux-modules-4.15.0-137-generic linux- modules-extra-4.15.0-137-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928744 Title: Disk IO very slow on kernel 4.15.0-142-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
